Cruise control not working

[Snels]

Anybody know why my cruise control would not be working? Nothing happens when I push any of the cruise buttons. I've checked a few things but I haven't come up with anything. The fuse is good. Brake lights work. Brake must be depressed to shift out of Park. Any help would be appreciated. 2002 F150 Supercrew Lariat.

1. Did you have the recall done ?

2. Did you run the self test ?
-----------------------

With the key off depress and hold the cruise control off button while turning the ignition to the run position,don't start the truck, the cruise light will flash once to let you know it is in self test.
Five additional flashes indicate a bad cruise control servo

Release the cruise off switch and within 5 seconds depress the other switches in sequence:
1. on
2. resume
3. coast
4. set/ accel
The speed control light will flash as each switch is depressed.

If the last one does not flash it may then flash a code

After this the cruise will move the throttle to test the actuator and the cable.
Make sure the throttle returns to idle and turn the key off.

Thanks for the info. I bought the truck a few months ago and the cruise control never worked. I did not personally have the recall done, but I checked the myford.com site with my VIN and it said "There are no outstanding recalls on your vehicle."

I did the self test and here's what I got - After holding the Off button and turning the ignition on the CRUISE light blinked. I then pushed ON, RESUME, COAST, and SET/ACCEL and the light blinked with each button. Immediately after the last blink the CRUISE light blinked two more times.

You said after the test the cruise will move the throttle. Should it actually move the gas pedal or just the throttle cable under the hood? I had my foot slightly rested on the pedal and did not feel it move.

Does this give you anymore ideas? Thanks for the help.

Note: While driving and trying to use the cruise control the CRUISE light does not come on at all.

The throttle cable under the hood is what is moved by the servo.
You might only notice a slacking in the pedal in the truck, would be hard to tell, you really need to look at the servo to the cable movement.

Did you read the post by projectSHO89 ?

— 2 flashes - BPP defective, circuit is defective, brake applied, CPP switch or jumper (if equipped).

BPP = Brake Pedal Position Switch
CPP = Clutch Pedal Position switch ( or jumper if it is an Auto trans ).

I did read projectSHO89's post about the 2 flashes. It said, "If the lamp does NOT flash with the last button, and additional flashes occur, follow the chart below for trouble codes:

— 2 flashes - BPP defective, circuit is defective, brake applied, CPP switch or jumper (if equipped)."

Mine did flash with the last button, then the 2 flashes followed. Does it still apply if I got a flash on the last button?

That would be my thought, that there is something up with the BPP, or the circuit.

The CC recall, you should have an additional fuse at the end of the plug on the master cylinder. Is that there ?

I don't have a whole lot of experience under the hood, but I'm willing to dig in. Can you tell me where I need to look to find the additional fuse?

Also, do you know how I would check the BPP?

I tried all the above things but nothing happens. When I turn the key to on while holding the off switch no cruise light comes on. Any other suggestions. Also checked all the fuses.

Thanks

Check fuses F5 and F13 in the passenger compartment fuse box.
